RegionFixer is not Python 3.10 compatible due to use of deprecated import in nbt.py

[sebkuip]

In the nbt.py file, the following import was done
from collections import MutableMapping, MutableSequence, Sequence

The importing of abc's from the collections library has been deprecated in python for a while. And has now been finally removed in python 3.10

Just updated regionfixer with your branch fix-python-3.10 and everything seems to work as expected. Thanks a lot @macfreek for your update.

@sebkuip I'm going to close this, feel free to reopen if needed.
